IVILLARD E. BROIVN, OF PHILADELPHIA, PENNSYLVANIA.

PLOW.

SPECIFICATION forming part of Letters Patent No. 310,249, dated January 6, 1885.

Application filed September 5, 1981.

To ctZZ whom it may concern:

Be it known that I. WILLARD E. BROWN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention has relation to plows intended for use in thick waXy soil, such as is usually found in the prairies of the \Vest; and it has for its object to provide efficient means by which to lubricate the polished surface of the mold'board in order that the soil will not stick thereon and impede the motion of the plow.

In the drawings, -Figure 1 is a side view of the mold-board side of my share attached to a standard and beam. Fig. 2 is an elevation of the inner side of the mold-board. Fig; 3 is a transverse section of the mold-board on line :0 .70, Fig. 2. Fig. 4 is a longitudinal section of the mold-board on line 9 y, Fig. 2, all of which will be described.

The mold-board A may be of any desired shape, and is by preference made of steel with a highly-polished surface. In the back of this mold-board I form the chamber B, about co- V extensive with the surface of said mold-board,

as shown. I prefer to form this chamber by means of a plate, 0, secured at its edges by rivets, or in other suitable manner, to the mold-board. This plate 0 is provided with an opening, 0, which is arranged, by preference, at about the middle of said plate, and communicates, therefore, with the chamber B at the middle portion of the latter. In operation I close this opening by a cover, D, sliding in guide 0', formed on the opposite edges of the opening 0. I fill the chamber B with packing E, of cotton-waste or other like substance suitable to carry oils. This packing may be placed in and removed from the chamber through opening 0, and by the central arrangement of said opening I am able to c011- (No model.)

venientl y and equally spread the packing in the chamber B. In practice I thoroughly saturate this packing with oil. This may be done before it is put in the chamber, or by turning it down on its side to the position in which Fig. 4 is shown and pouring the oil through the opening 0. This oil is passed through openings at through the mold-board, and is dis tributed over the surface thereof, lubricating it and preventing the clays from sticking. The shape and arrangement of these openings form an important feature of my invention. It will be noticed from Fig. 1 that the openings or are elongated transversely the direction of the mold-board, and are arranged in rows A, the openings of each row being arranged in line with each other, and the said rows being parallel to each other, as shown in the said Fig. 1. By this formation and the arrangement of the openings a of each row close together I 70 form almost continuous slots through the moldboard transverse the direction of the plow, and the oil passes through the openings a, and is distributed over the surface of the mold-board between each row A and the row next in rear, thus accomplishing a thorough oiling of the surface of the mold-board.

It is manifest that instead of a steel moldboard a wooden one might be used; but such would absorb and hold as much, if not greatly more, oil than would be distributed on its surface, and I prefer to use the steel or other metallic surface, because by same I secure the application and use of the entire quantity of oil for the desired purpose and prevent wastage, as will be seen. The packing in chamber B holds the oil and gives same off in sufficient quantities to serve the purpose, and deposits the oil slowly, preventing its running off more freely than is necessary.

Heretofore plow 1n old-boards have been perforated, and provided with chambers arranged on their rear side, into which oil has been poured, so it might flow through'the perforations in the mold-board. Air and water have 95 also been forced into such chambers, and the perforations in the mold board have been formed of slots elongated transversely to the line of motion of the plow, and arranged in a single row. These, broadly, are not my in- I00 vention. By their use the oil flows out freely, and is used in great excess of the necessity, re sulting in so considerable an expenditure for oil as to render the constructions above described impracticable in most instances.

My invention differs most essentially from the constructions referred to by the use of packing as a carrier for the oil, so that the same may gradually ooze off through the openings in such degree as will give good and the desired results, and yet will not flow out of said openings in a stream, as would be the case were the packing omitted.

My invention also differs from the constructions before referred to in the arrangement of the opening 0 into chamber 13, so the packing may be conveniently distributed through said opening. I do not therefore claim, broadly, a perforated mold-board, nor a mold-board having slots formed through it elongated transversely to the direction of motion and arranged in a single row, nor yet a perforated mold-board having 011 its rear side a chamber adapted to receive oil; but,

Having thus described my invention, what I claim, and desire to secure by Letters Pat cut, is-

1. A mold board having perforations or openings formed through it, and formed with a chamber, 13, on its rear side, and packing placed in said chamber, and adapted to carry oil and deposit same through the openings in the moldboard, substantially as set forth.

2. In a plow, the mold-board of metal, having a polished surface and openings formed through it, and provided in its rear side with a chamber, B, and packing held in said chamber and saturated with oil, substantially as set forth.

3. The improved moldboard made of metal, and provided with openings a, elongated transversel y the direction of the length of the moldboard, and arranged in parallel rows A, and provided on its rear side with chamber 13, having centrally disposed opening 0, having guides C G on its opposite edges, the packing held in chamber B, and the door or cover D, sliding in guides G, and adapted to close opening 0, substantially as set-forth.

In testimony whereof I affix my signature in presence of two witnesses.
